After understanding the assertion and reason, choose the correct option.

Assertion: In the bonding molecular orbital (MO) of H 2 , electron density is increased between the nuclei.
Reason: The bonding MO is ψA+ψB , which shows destructive interference of the combining electron waves.
  1. Assertion and Reason are correct, but Reason is not the correct explanation for the Assertion.
  2. Assertion and Reason are correct and Reason is the correct explanation for the Assertion.
  3. Assertion is incorrect, Reason is correct.
  4. Assertion is correct, Reason is incorrect.

Solution

Electron density between nuclei increased during formation of BMO in H2 .



BMO is ψA+ψB (Linear combination of Atomtextc orbitals) provides constructive interference.
While by distructive interference anti BMO ψ A − ψ B formed.
